A method for preparing fish oil having decreased fish odor, which comprises slightly hydrogenating fish oil under the following non-selective conditions: (1) an amount of catalyst used in the hydrogenation is 0.05% by weight or more to an amount of the fish oil; (2) hydrogen pressure in gaseous phase at the beginning of the hydrogenation is 3 kg/cm.sup.2 or more; (3) reaction temperature of the hydrogenation is in the range from 90.degree. to 150.degree. C.; (4) reaction time of the hydrogenation is in the range from 5 to 30 minutes. The fish oil is preferably sardine oil, mackerel oil, skipjack oil, tuna oil, skipjack orbital fat or tuna orbital fat.

    • A semiconductor device includes a MOSFET which has a source and drain region of a first conductivity type, and an ion implanted channel section, and a pair of threshold control sections having a second conductivity type, one being disposed in a substrate surface between the channel section and the source region and the other being disposed in the substrate surface between the channel section and the drain region, and each of the threshold control sections having an impurity concentration so high that a threshold voltage of the MOSFET can be controlled. The threshold voltage of the MOSFET is not determined by the impurity concentration in the ion implanted channel section but is determined by the impurity concentration in the threshold voltage control sections. This enables the adequate control of the threshold voltage of the MOSFET that is part of a MOS integrated circuit and the simplification of the manufacturing method of the MOS integrated circuit.
    • 半导体器件包括具有第一导电类型的源极和漏极区域以及离子注入沟道部分的MOSFET以及具有第二导电类型的一对阈值控制部分,一个设置在沟道部分之间的衬底表面中 并且源极区域和另一个设置在沟道部分和漏极区域之间的衬底表面中,并且每个阈值控制部分具有如此高的杂质浓度,使得可以控制MOSFET的阈值电压。 MOSFET的阈值电压不取决于离子注入通道部分中的杂质浓度,而是由阈值电压控制部分中的杂质浓度决定。 这使得能够充分地控制作为MOS集成电路的一部分的MOSFET的阈值电压以及简化MOS集成电路的制造方法。
